University of Miami Cox Science Lab: Sealed leaks in laboratory fume hood exhausts, which had been unable to adequately remove fumes from the labs

The University of Miami’s Cox science building was undergoing partial renovation. After testing dozens of fume hoods located in laboratories throughout the four - story building, the school’s environmental health and safety group found that many of the hoods were not providing sufficient exhaust. The reason: leaks in the connecting ducts and ventilation shafts.
